DETAILED DESCRIPTION

An image capturing optical lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. The image capturing optical lens assembly further includes an image sensor located on an image plane.

The first lens element with positive refractive power provides partial refractive power for reducing the total track length of the image capturing optical lens assembly so as to maintain the compact size thereof. The first lens element has a convex object-side surface, and can have a convex image-side surface or a concave image-side surface. When the first lens element has a convex image-side surface, the refractive power of the first lens element can be enhanced for further reducing the total track length of the image capturing optical lens assembly. When the first lens element has a concave image-side surface, the astigmatism of the image capturing optical lens assembly can be corrected, so that the image quality of the image capturing optical lens assembly can be improved.

The second lens element with negative refractive power has a concave object-side surface and a convex image-side surface. Therefore, the aberration generated from the first lens element with positive refractive power can be corrected.

The third lens element can have positive refractive power or negative refractive power. When the third lens element has positive refractive power, the sensitivity of the image capturing optical lens assembly can be adjusted. When the third lens element has negative refractive power, the high order aberration of the image capturing optical lens assembly corresponding to the second lens element can be reduced. The third lens element has a concave object-side surface and a convex image-side surface, so that the aberration of the image capturing optical lens assembly can be corrected. Moreover, the object-side surface and the image-side surface of the third lens element are aspheric.

The fourth lens element with positive refractive power can reduce the sensitivity of the image capturing optical lens assembly in accordance with the first lens element. The fourth lens element has a concave object-side surface and a convex image-side surface, so that the astigmatism of the image capturing optical lens assembly can be corrected. The fourth lens element is made of plastic material, and the object-side surface and the image-side surface thereof are aspheric.

The fifth lens element can have positive refractive power or negative refractive power. When the fifth lens element has positive refractive power, the total track length of the image capturing optical lens assembly can be further reduced. When the fifth lens element has negative refractive power with a convex object-side surface and a concave image-side surface, the principal point of the image capturing optical lens assembly can be positioned away from the image plane, and the total track length of the image capturing optical lens assembly can be reduced so as to maintain the compact size thereof. The fifth lens element is made of plastic material, and the object-side surface and the image-side surface thereof are aspheric. Moreover, the fifth lens element has at least one inflection point formed on at least one surface thereof, so that the incident angle of the off-axis field on the image sensor can be effectively minimized and the aberration can be corrected as well.

When a focal length of the image capturing optical lens assembly is f, and a focal length of the fifth lens element is f5, the following relationship is satisfied: −1.75<f/f5<0.50. Therefore, the refractive power of the fifth lens element can correct the aberration generated from the fourth lens element. Preferably, f and f5 can satisfy the following relationship: −1.3<f/f5<0.

When the focal length of the image capturing optical lens assembly is f, and a focal length of the third lens element is f3, the following relationship is satisfied: −1.3<f/f3<0.5. Therefore, the refractive power of the third lens element is proper for correcting the aberration of the image capturing optical lens assembly. Preferably, f and f3 can satisfy the following relationship: −0.5<f/f3<0.5. Moreover, f and f3 can satisfy the following relationship: −0.5<f/f3<0.

When a curvature radius of the object-side surface of the fifth lens element is R9, and a curvature radius of the image-side surface of the fifth lens element is R10, the following relationship is satisfied: |R10/R9|<1.0. Therefore, the astigmatism and the distortion of the image capturing optical lens assembly can be corrected by the curvature of the fifth lens element, and the incident angle on the image sensor can be reduced for enhancing the sensitivity of the image capturing optical lens assembly, and improving the photographic performance of the image sensor.

When an Abbe number of the first lens element is V1, and an Abbe number of the second lens element is V2, the following relationship is satisfied: 31<V1−V2<42. Therefore, the chromatic aberration of the image capturing optical lens assembly can be corrected.

When a curvature radius of the object-side surface of the second lens element is R3, and a curvature radius of the image-side surface of the second lens element is R4, the following relationship is satisfied: −1.8<(R3+R4)/(R3−R4)<−1.0. The curvature of the surfaces of the second lens element can corrected the aberration generated from the first lens element. Preferably, R3 and R4 can satisfy the following relationship: −1.5<(R3+R4)/(R3−R4)<−1.0.

When a curvature radius of the object-side surface of the first lens element is R1, and a curvature radius of the image-side surface of the first lens element is R2, the following relationship is satisfied: |R1/R2|<0.3. Therefore, the spherical aberration of the image capturing optical lens assembly can be corrected, and the total track length thereof can be further reduced.

When an axial distance between the second lens element and the third lens element is T23, and an axial distance between the fourth lens element and the fifth lens element is T45, the following relationship is satisfied: 0<T45/T23<0.5. Therefore, the fabrication of the lens elements can be easier due to the distance between of the lens elements.

When a curvature radius of the object-side surface of the third lens element is R5, and a curvature radius of the image-side surface of the third lens element is R6, and the following relationship is satisfied: −0.5<(R5−R6)/(R5+R6)<0.5. Therefore, the refractive power and the capability for correcting the aberration of the third lens element are proper by adjusting the curvature of the surfaces of the third lens element.

When an axial distance between the object-side surface of the first lens element and the image plane is TTL, a maximum image height of the image capturing optical lens assembly is ImgH, the following relationship is satisfied: TTL/ImgH<2.3. Therefore, the total track length of the image capturing optical lens assembly can be reduced so as to maintain the compact size of the image capturing optical lens assembly for portable electronic products.

When the focal length of the image capturing optical lens assembly is f, and a focal length of the fourth lens element is f4, the following relationship is satisfied: 0<f/f4<2.0. The refractive power of the fourth lens element is proper for reducing the sensitivity of the image capturing optical lens assembly corresponding to the refractive power of the first lens element.

According to the image capturing optical lens assembly of the present disclosure, the lens elements thereof can be made of glass or plastic material. When the lens elements are made of glass material, the distribution of the refractive power of the image capturing optical lens assembly may be more flexible for design. When the lens elements are made of plastic material, the cost of manufacture can be effectively reduced. Furthermore, the surface of each lens element can be aspheric, so that it is easier to make the surface into non-spherical shapes. As a result, more controllable variables are obtained, and the aberration is reduced, as well as the number of required lens elements can be reduced while constructing an optical system. Therefore, the total track length of the image capturing optical lens assembly can also be reduced.

According to the image capturing optical lens assembly of the present disclosure, when the lens element has a convex surface, it indicates that the paraxial region of the surface is convex; and when the lens element has a concave surface, it indicates that the paraxial region of the surface is concave.

According to the image capturing optical lens assembly of the present disclosure, the image capturing optical lens assembly can include at least one stop, such as an aperture stop, glare stop, field stop, etc. Said glare stop or said field stop is allocated for reducing stray light while retaining high image quality. Furthermore, when the stop is an aperture stop, the position of the aperture stop within an optical system can be arbitrarily placed in front of the entire optical system, within the optical system, or in front of the image plane in accordance with the preference of the optical designer, in order to achieve the desirable optical features or higher image quality produced from the optical system.
